OTC CGM HSA FSA Eligibility
Eligible ExpensesA Dexcom Stelo subscription costs $1,068 per year, but you could save $250 or more by using pre-tax FSA or HSA funds. Understanding OTC CGM HSA FSA eligibility is key for anyone using a high-deductible health plan or flexible spending account to manage metabolic health. Since the CARES Act passed in 2020, over-the-counter continuous glucose monitors have qualified as medical expenses without a doctor's prescription, a rule that continues for the 2026 plan year. This guide explains how to use your tax-advantaged accounts for these devices, addressing common confusion about IRS rules and plan administrator specifics.

In Context
For W2 employees with HDHPs and self-employed individuals managing metabolic health, this eligibility allows the use of pre-tax dollars to purchase devices like Dexcom Stelo and Levels Lingo, directly reducing the effective cost by 20-30% and providing a clear path to fund tools not covered by

Why It Matters
For the niche audience of HDHP enrollees, self-employed individuals, and families maximizing tax-advantaged healthcare, OTC CGM HSA FSA eligibility matters because it directly addresses key pain points: fear of IRS audits over ineligible purchases and missing out on tax deductions. Understanding this specific rule turns confusion into a strategic financial advantage.
Common Misconceptions
- A common misconception is that all CGMs require a prescription to be FSA/HSA eligible. The CARES Act changed this for OTC devices, but many people still assume they need a doctor's note.
- Many believe their FSA or HSA debit card will automatically work for any online medical purchase. In reality, some vendors' payment gateways may not be coded correctly, requiring a manual reimbursement claim.
- Some think OTC CGM eligibility might be a temporary COVID-19 rule. The CARES Act provision is permanent, and OTC CGMs remain eligible for the 2026 plan year and beyond.
Practical Implications
- You can budget your FSA election or HSA contributions to include the annual cost of an OTC CGM, knowing it's a qualified expense. For 2026, this means allocating part of your $3,400 FSA or $4,300/$8,550 HSA limit.
- It simplifies purchasing for non-diabetic users who would otherwise have no insurance pathway to access glucose monitoring, making metabolic health tracking more financially accessible.
- HR benefits managers can educate employees about this eligibility as part of open enrollment, highlighting how FSAs/HSAs can be used for a wider range of modern health tools.
- Financial advisors have a concrete example to show clients how HSAs can be used for current qualified expenses while also serving as long-term investment vehicles for retirement healthcare costs.

Pro Tips
Before buying, confirm with your FSA/HSA administrator that OTC CGMs are eligible under your specific plan. Some administrators maintain their own lists of approved items.
If using an FSA, plan your OTC CGM purchase around the plan year and carryover limit. A $1,068 annual cost is significant relative to the $3,400 limit, so factor it into your annual election.
Buy sensors in multi-month packs for better value. Dexcom Stelo's 3-month autoship plan brings the monthly cost down to $84, saving you $60 per year compared to the monthly subscription.
Always save your itemized receipt showing the device name, date, and amount. For online purchases, the order confirmation email often suffices for reimbursement claims.
Consider the long-term investment potential of an HSA. If you can afford to pay for the OTC CGM out-of-pocket, you can leave your HSA funds invested for future growth and reimburse yourself later, even years down the line.
Frequently Asked Questions
Are over-the-counter CGMs like Dexcom Stelo eligible for FSA and HSA reimbursement?
Yes, over-the-counter CGMs are eligible for reimbursement from FSAs and HSAs. The CARES Act of 2020 permanently expanded the definition of qualified medical expenses under IRS Code Section 213(d) to include OTC medical devices without a prescription. This means devices like Dexcom Stelo and Levels Lingo, which received FDA clearance in 2024, qualify. However, final approval depends on your specific FSA or HSA plan administrator, so you should verify with them before purchasing.
Do I need a prescription or Letter of Medical Necessity for an OTC CGM?
No, you do not need a prescription or a Letter of Medical Necessity (LMN) for an OTC CGM to be FSA or HSA eligible. This is a key difference from prescription CGMs like the Dexcom G7, which typically require an LMN for insurance coverage. The CARES Act removed the prescription requirement for OTC items. You can buy an OTC CGM directly from the manufacturer or retailer and use your tax-advantaged funds, provided you have a qualified medical condition like prediabetes or reactive hypoglycemia.
How much can I save by using my FSA or HSA for an OTC CGM?
Using pre-tax FSA or HSA funds typically yields a 20 to 30 percent savings, depending on your federal and state tax brackets. For example, on an annual Dexcom Stelo subscription cost of $1,068, your net savings would be between roughly $250 and $270. This effectively reduces the out-of-pocket cost. Remember, FSAs have a use-it-or-lose-it rule with a $680 carryover cap, while HSA funds roll over indefinitely, giving you more flexibility for larger purchases.
Can I use my FSA or HSA debit card to buy an OTC CGM online?
Yes, in most cases you can use your FSA or HSA debit card (which is typically a standard Visa or Mastercard) to purchase an OTC CGM directly from vendor websites like stelo.com or hellolingo.com, or from eligible retailers like Amazon or Walgreens. If the transaction is coded as a medical expense, it will go through. If your card is declined, you can pay with a personal credit card and submit the receipt for reimbursement from your FSA or HSA administrator. Always keep detailed receipts.
What is the difference between FSA and HSA eligibility for OTC CGMs?
The core eligibility rule is the same: both FSAs and HSAs follow the IRS definition of qualified medical expenses, so OTC CGMs qualify for both. The practical differences involve account limits and rules. For 2026, the FSA contribution limit is $3,400 per employee with a potential $680 carryover. HSA limits are higher at $4,400 for self-only and $8,750 for family coverage, with indefinite rollover.
Will my standard health insurance cover an OTC CGM?
Most standard health insurance plans do not cover OTC CGMs for non-diabetic or prediabetic users. These devices are designed for the consumer wellness market and are purchased directly. This makes FSA and HSA funds the primary funding source for individuals using them for metabolic insight without a diabetes diagnosis. Always check your specific plan details, as coverage for prescription CGMs for diabetes management is different and often requires meeting strict criteria.
Who is eligible to use FSA/HSA funds for an OTC CGM?
Eligibility extends to anyone with a qualified medical expense as defined by the IRS. This includes individuals with diabetes, prediabetes, or other metabolic conditions like PCOS or reactive hypoglycemia. The device must be used for the diagnosis, treatment, or prevention of a disease. General wellness use without an underlying condition may not qualify. The user must also be 18 or older, as current OTC CGMs like Stelo and Lingo are cleared for adults.
